Hi Nanda,

Thank you for contacting Mearto with your appraisal inquiry.
Many makers of these glass or crystal figures signed them, and there can be some broad variation in value depending on who made them. If you notice a signature (probably quite small and discrete and hard to see) please let me know and I'll update this appraisal (and re-evaluate if necessary).
